![]() * Illumination at time of impact: E=Earthshine, S=Sunlight Northern crater of group of 3, use central peakĭifferent shape, crater has collapsed terraces Tiny crater NE of U-feature, NW of Clausius Location and Description of Moon FeaturesĮarthshine-lit Pointing Checks, Offsetting to S1C-Rįresh basalt ring, easily recognized at Full Moon Spectra: To calibrate spectra, use locations of known or well studied mineralogy. Measurements through various filters are useful (for instance at 400, 450, 500, 550, 750, 900, 950, 1000 nm) or in infrared if you have that possibility. A list of mineralogy calibration craters is given in the table below. Images: To calibrate images, use mineralogy calibration targets. For the same 3 times, a close-up view of the region around the impact site is also given with the features from the above roadmap labelled. Click on image for the high-resolution version. The below set of images shows the phase of the Moon at 3 times: one day before impact, at the time of perilune on the forelast orbit and on the nominal impact time. To check pointing accuracy in Earth-shine lit Moon Lehmann C (if albedo Clausius too low in Earthshine)ĭrebbel D (if albedo Clausius too low in Earthshine) To verify pointing to locations on the Sunlit Moonīullialdus central peak (CP). Follow the bright Tycho ray to (RA,DEC) = (North,East) towards terminator ![]() When you are also taking images, it is useful to take images of the different features along the way, as these can be used for calibration. The details of the Moon features stated in the roadmap are given further down this page. It takes into account sunlit features on 3 September but can be adapted to other observing times. For observing the region of the Moon around the SMART-1 impact sites, a roadmap to navigate along with your telescope is set up. ![]()
